For the general understanding of CT, a distinction between the different techniques is necessary.
CT can be essentially:
- unaccompanied when the loading units (swap bodies, containers and semi-trailers) travel alone
- accompanied (Rolling Road) when the whole lorry is forwarded with its driver
Combined Transport is an efficient alternative to pure road transport insofar as it offers many advantages. In order to take fully advantage of it, more and more sophisticated production schemes have been developed by the CT operators.
